Three tools that help you write a drabble:
First, inspiration—the quick-writing groups on Gather.com offer plenty of suggestions;
second, a word-processor that looks for synonyms—too much repetition in so few words gets boring;
and third, a word-processor that counts your words, because reading will probably distract you from adding them up.
Two close relatives of drabbles:
The dribble, which is a mere fifty words long;
and the double-drabble, which comes in at two-hundred.
One feeble attempt to describe the attraction of drabbles:
They read like super-sized haikus, with words instead of syllables, and a hundred instead of seventeen.
